FURROW-COVERING MACHINE.

Specification of Letters Patent.

Patented July 25, 1911.

To all whom it may concern:

Be it known that I, FRANK BATEMAN, a citizen of the United States,residing in Grenloch, Camden county, New Jersey, have invented certainImprovements in Furrow- Covering Machines, of which the following is aspecification.

The object of my invention is to provide a furrow covering machine withmeans whereby the proper action of the covering blades in returning theupturned earth to the furrow will be insured and the proper filling ofsaid furrow from end to end thus effected. This object I attain in themanner hereinafter set forth, reference being had to the accompanyingdrawing, in which-- Figure 1 is a plan view of sufficient of a furrowcovering machine to illustrate my present invention, and Fig. 2 is arear View showing the parts constituting my invention in the relationwhich they bear to the furrow during the operation of the machine.

In the drawing, 11 represent the opposite covering or turning-in blades,whereby, as the machine is drawn forward, the earth upturned in formingthe furrow is turned back into the same after the seeds have beendeposited, these blades, in the present instance, consisting of disksrotatably mount ed upon spindles 2, which are adjustably secured to theopposite end portions of a transverse bar 3, the latter being secured toa frame or yoke 1, which extends downwardly and rearwardly from the axle5 of the machine, and is pivotally mounted, at its forward ends, inhangers 6 depending from said axle, the latter and its supporting wheels7 being shown by dotted lines in Fig. 1.

The rear portion of the yoke 1 and its transverse bar 3 are connected,by links 8, to any suitable suspending and adjusting device, whereby thecovering blades 1 are maintained in proper vertical position to act uponthe banks of earth turned up on each side of the furrow, as indicated byclotted lines in Fig. 2, the yoke and bar thus serving as a carrier forthe covering blades.

As furrows of different widths may have to be covered, the coveringblades 1 are adjustable laterally on the spindles 2, the outer end ofthe hub of each blade bearing against a sleeve 12, which has a series ofopenings 13, to any one of which may be adapted the bolt 14:, wherebythe sleeve is secured to the spindle, lateral adjustment of the sleeveon the spindle being thus provided for.

In order to properly perform their intended function, the coveringblades 1 should always be drawn forward in line with the furrow, sincedeflection of said blades to one side or the other will necessarilyprevent the proper turning into said furrow of the banks of earth thrownup on each side of the same, the furrow being consequently leftuncovered or only imperfectly covered where such deflection occurs.

To insure such right relation of the furrow-covering blades to thefurrow, therefore, as the machine is drawn forward over the field, Ilocate in the furrow, in advance of said blades, a guide which, byengagement with the sides of the furrow tends to prevent any lateraldeflection of the machine and thereby maintains the furrowcoveringblades in their proper line of draft.

While many forms of guide adapted to run in the furrow and so connectedto some member of the machine as to exert the desired lateral retaininginfluence thereon may be adopted in accordance with my invention, Iprefer to use for the purpose a pair of rotating wheels or disks 9,mounted upon the blade-carrying member of the machine and engaging withthe opposite sides of the furrow, as shown by the dotted lines in Fig.2, whereby they will offer such resistance to lateral displacement aswill tend to prevent deflection of the blade-carrying member of themachine to one side or the other to an extent sutficient to carry thecovering blades out of position to engage with the banks of earth turnedup at the sides of the furrow. These disks are preferably inclined inrespect to the vertical so as to bear upon the sides of the furrow moredirectly than would such vertically disposed disks and each disk isproperly mounted upon its respective member of the yoke 4 so as to beara normally fixed lateral relation thereto, the means adopted in thepresent instance for effecting this result being an arm 10, secured, atits upper end, to said member of the yoke and carrying, at its lowerend, the spindle upon which the disk 9 is mounted, said arm beingrigidly retained in its proper position by means of a brace 11,extending from the arm to the side member of the yoke, as shown in Fig.1.

Each member of the yoke 4 has a series of openings 15, to any one ofwhich may be adapted the bolt '16, whereby the disk-carrying arm 10 issecured to said member of the yoke, and, in like manner, the yoke memberhas a series of openings 17 for the reception of the bolt 19, wherebythe brace 11 is secured thereto, provision being thus afforded foreffecting lateral adjustment of the disks 9, to suit different widths offurrow, or, if the brace 11 only is readjusted, for effecting change inthe vertical position of said disks.

I claim l. The combination, in a furrow covering machine, of a pair ofcovering blades, a carrier upon which said blades are mounted, saidcarrier having wheels which at all times support the carrier as it isdrawn forward and a guide also mounted on said carrier and running inthe previously formed furrow in advance of the covering blades.

2. The combination, in a furrow covering machine, of a pair of coveringblades, a carrier upon which said blades are mounted, said carrierhaving wheels which at all times support the carrier as it is drawnforward and a pair of disks also mounted upon said carrier and eachengaging with its respective side of the previously formed furrow inadvance of the covering blades.

3. The combination, in afurrow covering machine, of a pair of coveringblades, a car rier upon which said blades are mounted, said carrierhaving wheels which at all times support the carrier as it is drawnforward, a pair of disks also mounted upon said carrier and eachengaging with its respective side of the previously formed furrow inadvance of the covering blades, and means for adjusting said disks fromand toward each other on said carrier.

4. The combination, in a furrow covering machine, of a pair of coveringblades, a carrier upon which said blades are mounted, said carrierhaving wheels which at all times support the carrier as it is drawnforward, a pair of disks also mounted upon said carrier and eachengaging with its respective side of the previously formed furrow inadvance of the covering blades, means for adjusting the covering bladesfrom and toward each other on said carrier, and means for adjusting thefurrow engaging disks from and toward each other on the carrier.

5. The combination, in a furrow covering machine, of a pair of coveringblades, a carrier upon which said blades are mounted, said carrierhaving wheels which at all times support the carrier as it is drawnforward, a pair of disks also mounted upon said carrier and eachengaging with its respective side of the previously formed furrow inadvance of the covering blades, and means for eflecting verticaladjustment of the disks upon the carrier.

6. The combination, in a furrow covering machine, of a pair of coveringblades, a carrier upon which said blades are mounted,

said carrier having wheels which at all times support the carrier as itis drawn forward, a pair of disks also mounted upon said carrier andeach engaging with its respective side of the previously formed furrowin advance of the covering blades, means for effecting verticaladjustment of the disks upon the carrier, and means for adjusting saiddisks from and toward each other on the carrier.

7 The combination, in a furrow covering machine, of a pair of coveringblades, a carrier upon which said blades are mounted, said carrierhaving wheels which at all times support the carrier as it is drawnforward, and a pair of disks also mounted upon said carrier and eachinclined in respect to the vertical, each disk engaging with itsrespective side of the previously formed furrow, in advance of thecarrier blades.

8. In a furrow covering machine, the combination of the covering blades,a suspended yoke upon which said blades are mounted, said carrier havingwheels which at all times support the carrier as it is drawn forward,and disks mounted upon the side members of said yoke and serving, byengagement with the sides of the previously formed furrow, to preventlateral deflection of the covering blades.
